If the range is to be used on LP gas, a qualified LP installer must convert it. We recommend that the range
be converted before installation.
For proper operation, the pressure of natural gas supplied to the regulator must be between 6’’ and
10’’ of water column (1,49 and 2,49 kPa).
For LP gas, the pressure supplied must be between 12’’
and 13’’ of water column (3 and 3,24 kPa).
When checking for proper operation of the regulator,
the inlet pressure must be at least 1’’ (0,25 kPa) greater
than the operating (manifold) pressure as given above.
The pressure regulator located at the inlet of the range
manifold must remain in the supply line regardless of
whether natural or LP gas is being used.
A flexible metal appliance connector used to connect
the range to the gas supply line should have an I.D. of
½’’ and be 5 feet (1,5 m) in length for ease of installation.
The gas regulator on the appliance is set at the factory
for pressures given by regulations.
For the La Cornue ranges and hobs the regulator and the pressure tap can be found on the hob’s manifold
located by the 2 left gas burners
Connect the Range to the Gas Supply
Shut off the main gas supply valve before disconnecting the old
range and leave it off until the new hookup has been completed.
Don’t forget to relight the pilot on other gas appliances when you
turn the gas back on.
Because hard piping restricts movement of the range, the use of a
CSA International certified flexible metal appliance connector is
recommended unless local codes require a hard piped connection.
Never use an old connector when installing a new range. If the hard
piping method is used, you must carefully align the pipe; the range
cannot be moved after the connection is made. To prevent gas leaks,
put pipe joint compound on, or wrap pipe thread tape with Teflon* around, all male (external) pipe threads.

Install a manual gas line shut-off valve in the gas line in an easily accessed location outside of the range.
Make sure everyone operating the range knows where and how to shut off the gas supply to the range.
Connect flexible metal appliance connector to the adapter on the range. Position range to permit
connection at the shut-off valve.
When all connections have been made, make sure all range controls are in the off position and turn on the
main gas supply valve.
Use a liquid leak detector at all joints and connections to check for leaks in the system.
Use a product specifically manufactured for leak detection. Leak testing of the appliance shall be
conducted in accordance to the manufacturer’s instructions.
